Export
Ask for the size you need — a post, a story, a square, 4K, 8K, or a pair of numbers you type — and Fractaria computes it again at that size rather than enlarging what was on screen. It tells you what the job will cost before it starts, then gets on with it without locking anything: the window is not modal.
Eight of the ten entries in the size menu are names with their numbers attached — Instagram post — 1080 × 1350 (4:5), Landscape — 3840 × 2160 (4K) — so you pick where the image is going and the width and height follow. Type your own numbers instead and the menu says Custom.
The export window carries a small render of your view, and the shape you chose sits on top of it: everything outside goes dark, thirds guides inside, the way a crop tool works. Drag it to move, pull the bottom-right corner to resize — it never loses the ratio. Move the view in the main window and the preview follows it.
Antialiasing goes up to 4×, which is sixteen samples a pixel, so the fine filaments stay clean when you go big. And it tells you what the job will cost before you start it: megapixels, megapixels sampled, memory — plus how far the frame crops into the view, and a warning when at that size the graphics card runs out of precision margin and the CPU takes over.
What comes out
The export is not the screen image scaled up. The whole frame is computed again at the size you asked for, which is why a filament that was one soft pixel on screen arrives as a drawn line at 16,384 pixels on the long side.
The iteration ceiling is the engine's
Not a lower copy of it left behind in the export window. What you can ask the export for is exactly what the renderer can do, so a deep view does not quietly lose its detail on the way out.
You can call it off
A big export takes as long as it takes, and while it runs there is a progress bar and a Cancel that stops it where it is and writes nothing.
There is a ceiling, and it is stated
16,384 pixels a side — the width and height fields will not take a bigger number — and a little over two hundred megapixels in total, because the output buffer stops at 600 MB. Past that the cost line turns orange and says too large: reduce the size, and Export… goes out instead of starting something it cannot finish. A 16,384 square is over that line; a 16,384 × 8,000 is not.
Three formats, four choices
PNG when it has to be lossless, JPEG when it has to be opened by anything, and WebP twice — lossless, which does the PNG's job in less space, and lossy. The quality slider only means something on the two lossy ones: with PNG and WebP lossless it dims and stops taking input.
The file is not the only way out
Export… writes the file. Copy puts the same image on the clipboard — same framing, same size, same signature — with no file and no dialog. If the system will not take it, it says so instead of failing quietly.
A signature, if you want one
Your own text, stamped in a corner of the file you save and nowhere else — not in the live view, not in the thumbnails. It is off until you turn it on, and its three sizes are fractions of the image height, so it weighs the same on a 1080-pixel post and on an 8K frame.
One purchase, everything included — the animation editor too, not a tier above it. No subscription, no unlocks: every fractal, every palette and every export size the application can make, from the first run.
